According to the conversion guide it is possible to simply swap the gearbox output flange to use the smaller flange, allowing the use of an m20 prop.

Ive removed both flanges and the splines are a different size!

Am i missing something here or is it because this was originally a 316 box? Are the splines for an m20 box bigger?

Must be from a 325i or as you say the splines are different.

A friend has a spare m20 box, will check it out tomorow
